Just when you think you just got to keep the coring sealed and dry you gotta watch for termites getting in it.

Wow, it's been a crazy couple of weeks, we are really working hard, and I'm taking pictures, but I can't find time to post. So this one should have probably been about 4 or 5 posts! And then Christmas, and of course I had to go visit the Alamo too (and rent a new corvette) so December was crazy. So here we go

We finally got the rear ice chests installed under the windows. I found a really good company that doesn't give me any trouble shipping to Costa Rica, and really they weren't that bad. The unit is called IsoTherm, and they are around 850 bucks for the compressor and the big element. They should both be able to freeze or refridgerate, I'm going to do one of each though. They ended up looking smaller than I wanted installed, it's weird because on the bench they looked soo big. I guess I'm just used to working on smaller boats, but either way, we'll put a big pad on top and that'll grow them a bit. They have about three inches of injected foam, plus they are made out of foam, so hopefully with the freezer element in each, they will get our beers and cokes cold!


I'm hoping they look bigger with the pad on them. That ladder is coming off of the left side, but we haven't gotten the tower built yet. We are going to climb up the tower leg and get more cokpit space.

This is a mid process shot of injecting them. We got ahold of some crummy foam, it didn't grow like foam I've used in the past. It did grow though and work, but I ended up with alot more holes.

And then we got the holes capped back up and the fairing done.

Sometimes the things that take the longest are the most unimpressive. The transom was a mess of rotten wood, a big heavy door, and no live bait area. We threw the door out to make room for a huge live well and tuna tube area. And then it took quite a bit to make the transom look normal again. I'll have to go back out and take some more pictures in a bit, these are about a week old, but this is kind of the idea

And then the tubes we did something cool. Instead of the typical PVC setup most people put in the bottom of the tubes, we left the bottom of the tubes open and 1.5 inch, and just put a short 2 inch run of pvc in the tube. But that didn't connect to anything. Then, we put them in a sealed box, one on each side, and then have a 4 by inch box connecting both sides, that we inject the water into. Here's our engineering drawing:

The idea is that the water pressure equals out and all the tubes flow the same. And, there is no PVC to bust later. That is always a problem for me, a few years in the PVC leaks, or the valves get stuck. So all that is eliminated and the flow is equaled out across the tubes. And they overflow into the live well, so one pump can do both the live well and tuna tubes.

And then I did something which I'm sure some people won't like. I painted the boat Dukes of Hazzard orange. Besides the fact that I loved watching that growing up, i figured that we will probably catch pretty good fish compared to most of the boats around us. And then people on other boats will notice the bright orange boat next to them that is always hooked up. And when they look for me in the marina afterwards, there will only be one bright orange boat.

And then we are playing with the window, not quite right yet but closer

Then I have a different crew working on redoing the roof. Harold brought his dad out from Puntarenas to help us get finished before February. His dad wanted to do the roof. So we started by making the tube that holds the actual top. I copied the old roof, which was rotten small aluminum tubes, and we went with a big fat tube.

I believe a few posts back I showed how we got the arc on the first sheet of foam. We used the same arc formula to make the bent on the tube so it has a nice arc too, and then cut the front with the same line. Then we mounted the aluminum tube on the faom, and doubled up the foam around the tube so the tube sinks into the roof. And then the top of the roof will have crown (arc), but the bottom will be flat so that it's hollow so I can run wiring. The first picture is a roof I helped Harold with earlier this year. It's kind of the same, but not really. And then the second picture is the roof we are building. It's a process shot, so not polished and finished but you get the idea.

I really tried not to. I have kids too, so I know we'll use the swim platform. But I couldn't get the live well to fit with the tubes, we tried twice and it looked terrible. With the door out, now I really like the look. But believe me, i tried to leave the door in, i get how useful it could have been.

Yeah, I put the foam in a old building that was full of termites, so it's kind of my fault. I don't think they went looking for the foam, but there were just so many of them.. On a bright note, I'm noticing that they didn't eat too much of the foam, I bet it killed the poor suckers that munched on it. The wood around the foam is just dust though.

Did you consider that every crappy fishermen in the fleet will see your boat from miles away and follow you around like a fat kid on a cupcake? I know a few highliners that had colored hulls that wished they went to white.

That's what I'm hoping for. On the troll the good boats will catch fish right next to the junk boats, it'll give their customers a better view! It'll save me a radio call trying to get them closer

I don't think I could get away with the battle flag, but I bet we could get the horn on it I asked the Coast Guard, they are a no go on the 01 too. At least I got my orange.

Not sure if you fallow Captain Glen on Instagram but his old boat “Floridian” was a bright orange and I loved the look of that boat. Rag’s

My brother lives and fishes out of Stuart, and the Floridian seems to have a bunch of “Friends” around him all day, that’s one of the highliners I was thinking of.

Wow you guys have been busy!
The bait tank arrangement with the tubes is awesome! Great thinking!
happy New Year everyone.

Ha, I get it now. In Florida I think there are ALOT more boats and that's the difference. Here it's just too small a community and if somebody asks you on the radio where you are and you don't tell them, you are in trouble for the rest of the year. We probably have 10 boats that fish out there most days (75 percent of the year), I'd bet there are thousands out of Florida most sunny days. I mean sometimes the private guys move their boats, but they usually do stupid things anyways, like make the 100 mile run out to the FADS when the fish aren't out there, and just run out 50 miles even when the bite is close. So I can definitely see what you were getting at now.

A little more progress. Maybe this shows how ghetto I am, we just quickly stuck some PVC inside the roof before we put the bottom on it. We are putting 4 LED color changing lights in the rood, a spreader light in the back, and then one day when I'm not so broke, we are going to add a big LED light bar up front. I'm going to do it the easy way, and bring all the cabling up through a dedicated tube right from the top of the console, and then I'll run the wires out to where they go in the PVC. Here's the tubes we glued up under the top:

Then we put the top on the thing with another layer of 1 inch foam

And then I did all the fairing, or at least put it on. We will sand it in a few minutes when it dries. The hole is where all the PVC's run to, so I can wire it once we install it.

Then, we decided to put that space to use in the cabin up front. I wanted somewhere to mount the speakers and a TV. I'm not sure what I'm going to put there still, I'm thinking either a computer with a touch screen, or a wall mounted Imac. Something that can watch videos either way. And then we'll put a marine stereo and speakers in as well. But something is going to be mounted on the right (starboard) side.

Pretty much all that is left is fairing and painting. The tower guys are slow slow slow, but I'm really hoping to get them over to the boat so i can install my top and get it all wired up. I'll try to post on here more too as I get a ton of DM's asking when the next pictures are coming!

Talking

Sorry for the lack of pictures, it's been a day and night type of deal lately. Pretty much everything is getting close now, but nothing is finished. First thing we did was a bunch of fairing. We would paint primer on thick with a brush, sand it with 100 grit, and then use a pencil to circle any imprefections and then use body filler to fill the spots.

And then we masked off the area that we will put non slip

Then masked off the orange to keep it orange. We still haven't hit that with the final two passes of sandpaper

And then we started painting!!! Just primer, but Monday we will do the topcoat I believe

The inside too, but not the top yet as they are still welding up there. But the bridge is ready for paint once they get done welding either tomorrow or Monday.

We had a guy working on the hard top too lately. All the speaker and light holes are cut out. We are going with 4 LED color changing lights in the hard top, a pair of Rigid lights to light the cockpit when we need bright lights, and then 4 fusion audio speakers in the top, and 2 in the top of the cockpit. We will have a seperate cabin radio with 4 speakers as well, and the outside radio will have 6 speakers. I'm going with the JBL marine head units. They are the round ones, and they are really easy to connect to via bluetooth, so the customers can play music off of their phones. The inside radio will be connected to the screen also, I'm thinking about getting a big tablet or touchscreen computer so people can watch movies on the overnight trips (or I can watch movies with the kids in the slip). Heres the bottom of the hard top:

Then we started on the doors. The doors are all foam cored, except for 1 inch on the side where the hinges go. We are putting in two pistons to shut the doors so you can just pull them open and walk in and they shut themselves. We are going to put two windows in them, that will line up with the side windows so it almost looks like one big window across the back. I thought about painting the space between the tinted plexiglass black too, but I think I'll leave it white for now.

And then we did the biggest thing to improve the quality of fishing. We are taking the ugly ladder out of the middle of the fishing area. It's going to be a bit harder to get upstairs, but we are going to build something to grab onto to make it easier. I lowered the ladder part on one side (it used to have one of those ridiculously high perches). It's hard to explain, but we just cut the base off of one of the ladders and welded it onto the foot. I like how it turned out, although I'm sure there will be some that don't. The cockpit is HUGE now, and it's now it's a fishing boat.

Last little bit of fairing and paint prep tomorrow and then we'll shoot the final topcoat hopefully Monday. And then we move to the wiring and plumbing stage, but there isn't too much to wire as most of the household type of things we are taking out.

On a side note, I was thinking of putting in a 10KW battery out of a wrecked tesla to power the AC during our day trips. We could charge at night, and then run the AC all day without turning on the genset. Maybe just turn the genset on when we need to cook, and then go back to battery power. That might be a whole seperate forum post, but it's something I'm figuring out now.

And then I'm trying to have fun with the build and boat afterwards. We are putting 4 LED color changing lights and 4 speakers in the hard top, but also 3 LED color changing lights in the cockpit with a pair of speakers. I thought if I mounted them over the door and windows, they would last the longest. And then I bought some LED light strips to put under the gunnel and probably under the bridge "hat". I'll wire it all together so they all come on together and change colors together. They do blue, red, green or white, so we can mix it up.
